IWC Watch box for 10 watches reference number

In the past IWC made watch boxes for 12 watches. (3 rows for 4 watches each)
The reference is IWA05945. They are black from the outside and white from the
inside. I bought a couple of them in 2006. Yet, the faux black leather starts
to come loose when touched. Well the is is in fact the case with all older
white (and black) IWC boxes.

There are also IWC watch boxes for 10 watches. (2 rows for 5 watches each).
They are black from the outside and grey 'suede' from the inside. They are the
successor of 'my' boxes. Does anybody know the reference number of this 10
watch box?

Cheers and thanks, Michiel

I have the same problem with my 12-watch-box.

Do you know from which year this the 10-watch-box?

Hi, my Workbook Collection ends with 2015/2016 and before I could not find any
reference of the box I bought recently.

So my guess is after 2016 but perhaps an other member can elaborate.

In the 2016/2017 Workbook are only a 6-watch-box.

I havn't any eccess to my other workbooks actually.

I use collectorsboxes for four watches (super because the box holds
travelpouches as well)

Nice one. :-)
